EXCLUSIVE

Amber Laura won't be returning to "Love and Hip Hop: Hollywood" next season and says it's all because her co-star Milan Christopherhas been dragging her name through the mud to show execs.

Amber's rep tells us she found out she got the ax for season 3 when a call sheet didn't come her way. The rep called network execs but they were radio silent, and eventually the word came down ... Amber was out.

It's a twisted situation ... Amber's boyfriend, Miles Brock, left her for Milan. Milan trashed Amber on Twitter saying she just used Miles to get on the show. Milan says Amber knew Miles was gay all along.

According to Amber ... the relationship between Milan and Miles was fake -- just to bring a "gay relationship" into the show -- and she says that relationship is already kaput, ending on very bad terms.
